Introduction: We find arguments of Béarez et al. unconvincing. We did not contend that Galeichtys peruvianus is a topical species. Rather, G. peruvianus was selected for its wide temperature tolerance and was captured during both El Niño and La Niña events in Huanchaco, Peru. The northern range boundary Béarez et al cite (6°S) is incorrect. In a prior publication Béarez stated that this species is native to Ecuador, an observation corroborated by other authors, which undermines the cool climate suggestion. Our sea surface temperature (SST) conclusions rely on δ18O data, not the presence or absence of species [although presence-absence data show predominantly tropical fauna at Ostra and Siches]. . .
